The following describes any modifications and/or deviations to the applicable test methods. If alternative methods were requested, see the attachments for documentation of request AND approval, including dates. Method 26A was modified to collect HCN with the HCL and HF.The concentration of the sodium hydroxide solution used was increased from 0.1 N to 1 N (or higher), an additional impinger containing sodium hydroxide was added to the train (three impingers instead of two), the pH of the impinger solutions was monitored periodically throughout the sample run. This modification was addressed on the Utility ICR website in the Frequently Asked Questions area (Question Test-025).
